top VS bottom mount M20 manifold?

Postby Dot Communist » Fri Jul 03, 2009 3:02 am

I am definatly going log style if I build a manifold, but I cant decide what would be better. I know bottom mount would be easier to fabricate and probably be stronger, but would I have have oil drain issues? Top mount would be a little harder to fab but it looks way cooler and probably fits the best? I dont really know either way right now because 90% of all e30 turbos I have seen are top mount, BUT if all else fails I'm fabbing up a top mount adapter :mrgreen:

You pretty much have all the facts. If you want AC you should go top mount. Bottom mounts tend to have oil draining problems. Thats kinda why I went top mount. Plus I 'd hit the subframe. Generally, theres more space up top. Unless youre an E36
